Abstract

A system ( 36 ) provides a network designer with a mechanism for analyzing the performance of a code division multiple access wireless network ( 20 ). The system ( 36 ) includes executable code in the form of a probable server identification module ( 52 ), a forward link initial estimation module ( 54 ), a reverse link initial estimation module ( 56 ), a forward link analysis module ( 58 ), and a reverse link analysis ( 60 ). The modular architecture of the modules ( 52, 54, 56, 58 , and 60 ) are appropriately configured and interconnected in order to form a network performance analysis process ( 62 ) that accurately analyzes both the reverse link performance and the forward link performance of the network ( 20 ).

Claims (26)

1. A computer-based method, in a network planning tool, for analyzing a performance of a digital wireless network defined by locations, said method comprising:

identifying probable servers for said locations in said network;

performing an initial reverse link assessment of said network to produce initial reverse link output parameters;

executing a forward link analysis in response to said performing operation utilizing said initial reverse link output parameters as inputs for said forward link analysis; and

implementing a reverse link analysis in response to said executing operation, wherein said executing operation comprises generating at least one of a plurality of forward link quality figures to analyze said performance of a forward link of said network.

2. A computer-based method as claimed in claim 1 wherein said plurality of forward link quality figures includes a forward link in-cell supported load value, an outage load value, a forward margin value, and an interference margin value.

3. A computer-based method as claimed in claim 1 wherein said implementing operation comprises generating at least one of a plurality of reverse link quality figures to analyze said performance of a reverse link of said network.

4. A computer-based method as claimed in claim 3 wherein said plurality of reverse link quality figures includes a reverse link margin value, a reverse link noise floor elevation value, a percentage of pole capacity value, a frequency reuse efficiency value, an in-cell supported load value, a mobile station transmit power value, and an updated list of probable servers for each of said locations in said network.

5. A computer-based method as claimed in claim 1 further comprising:

determining one of a forward link and a reverse link is a limiting link; and

conducting said performing, executing, and implementing operations when said forward link is said limiting link.

6. A computer-based method as claimed in claim 5 further comprising:

performing an initial forward link assessment of said network when said reverse link is said limiting link;

implementing said reverse link analysis in response to said initial forward link assessment; and

executing said forward link analysis in response to said reverse link analysis.

7. A computing system, in a network planning tool, for analyzing a performance of a digital wireless network defined by locations, and said computing system comprising:

a processor;

a computer-readable storage medium; and

executable code recorded on said computer-readable storage medium for instructing said processor to analyze said performance of said network, said executable code including:

a probable server identification module for identifying probable servers for said locations in said network;

a reverse link initial estimation module for providing an initial reverse link assessment of said network, said, initial reverse link assessment producing initial reverse link output parameters;

a forward link initial estimation module for providing an initial forward link assessment of said network, said initial forward link assessment producing initial forward link output parameters;

a forward link analysis module for analyzing a forward link performance of said network, said forward link analysis module utilizing said initial reverse link output parameters as inputs for said forward link analysis; and

a reverse link analysis module for analyzing a reverse link performance of said network, said reverse link analysis module utilizing said initial forward link output parameters as inputs for said reverse link analysis, wherein:

said forward link analysis module analyzes said forward link performance in response to one of said initial reverse link assessment and said analyzed reverse link performance; and

said reverse link analysis module analyzes said reverse link performance in response to one of said initial forward link assessment and said analyzed forward link performance.
